Lisa [10]

Answer:

3.5%

Step-by-step explanation:

In this case, the final probability would be the product of the two probabilities that the plating shows us:

First probability would be:

We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25

Second probability:

We are told that 14% collected insects, therefore it would be 0.14

The final product is the question they ask us:

0.25 * 0.14 = 0.035

Which means that the joint probability is 3.5%

An election forecasting model has a 50:50 chance of correctly predicting the election winner when there are two candidates. Befo

Blababa [14]

Answer:

Te correct answer is c) 0.750

Step-by-step explanation:

Lets call:

A = {Allan wins the election}

B = {Barnes wins the election}

MA = {the model predicts that Allan wins}

MB = {the model predicts Barnes wins}

We know that the model has a 50:50 chance of correctly predicting the election winner when there are two candidates. Then:

P(MA | A) = 0.5 = P(MA | B)

P(MB | B) = 0.5 = P(MB | A)

The prior probability P(A) given by the election researcher is 0.75

We must find the posterior probability P(A | MB)

We use Bayes theorem:

$P(A|MB) = \frac{P(MB|A)P(A)}{P(MB)} = \frac{0.5*0.75}{0.5} = 0.75$

We used the result:

$P(MB) = P(MB|A)P(A) + P(MB|B)P(B) = 0.5*0.75+0.5*0.25=0.5$

zavuch27 [327]

Answer:

$2,341.27.

Step-by-step explanation:

Let x represent realized income for month.

It has been given that your housing and fixed expenses are 702.38 month. We are asked to find your realized income for the month if your fixed expenses are account for 30%.

This means that 30% of x is equal to $702.38. We can represent this information in an equation as:

$30\%\text{ of }x=\$702.38$
